Elon Musk Predicts This Will be the Next Wave of AI (Ad)

Nvidia CEO Jensen Huang says the Accelerated AI inflection has arrived. Elon Musk has predicted that 99 percent of compute long-term will be for Accelerated AI. Jeff Brown, the former tech executive who identified Nvidia in 2016 before its 37,800 percent run, is now pointing to a company he says has developed the most powerful Accelerated AI processor in the world. Wall Street projects its sales will triple by 2027, and the technology is backed by 150 patents. See the full research behind Jeff Brown's Accelerated AI picktc pixel

Short selling CLSK is an investing strategy that aims to generate trading profit from Cleanspark as its price is falling. CLSK shares are trading down $0.40 today. To short a stock, an investor borrows shares, sells them and buys the shares back on the public market later to return it to the lender. Short sellers are betting that a stock will decline in price. If the stock does drop after selling, the short seller buys it back at a lower price and returns it to the lender. The difference between the sell price and the buy price is the trader's profit.

A short squeeze for Cleanspark occurs when it has a large amount of short interest and its stock appreciates in price. This forces short sellers to cover their short interest positions by buying actual shares of CLSK, which in turn drives the price of the stock up even further.

Short interest is typically published by a stock exchange once per month. However, NASDAQ publishes a report for U.S. stocks, including CLSK, twice per month. The most recent reporting period available is August, 31 2026.

Understanding short interest metrics can help you assess how traders are positioning around a stock like CLSK:

  • Shares Sold Short: The total number of shares that have been sold by short sellers but have not yet been covered or closed out. A high number may indicate bearish sentiment.
  • Short Float: The percentage of a company’s publicly available shares (or "float") that are sold short. A higher short float suggests a greater portion of the stock is being bet against.
  • Days to Cover (Short Interest Ratio): This estimates how many days it would take short sellers to cover their positions, based on average daily trading volume. Higher values can signal potential for a short squeeze if buying pressure increases.

These metrics are often used by traders to gauge sentiment, volatility risk, and the potential for price movements based on short covering activity.
